Frequently Asked Questions About Roofing Companies
Find answers to common questions about roofing companies and hiring roofing contractors in the USA.
What is the difference between a roof overlay and a roof tear-off?
When replacing a roof, there are two main approaches: Roof Overlay: Installing a new layer of roofing material over the existing roof. It's less expensive and faster, but not always ideal. Roof Tear-Off: Completely removing the existing roofing before installing a new one. More labor-intensive but allows for inspection and repairs to the roof deck. A tear-off is typically preferred, but a roofing contractor can advise on the best approach for your situation.
What is a roof valley, and why is it important?
A roof valley is the internal angle formed where two roof slopes meet. It's a critical area for waterproofing, as it channels a high volume of rainwater runoff. Improperly flashed valleys are a common source of leaks, so it's crucial to ensure they are properly sealed and maintained.
What are some common signs of roof damage?
Common roof damage indicators:
Leaks or Water Stains: Water stains on ceilings or walls, dripping water, or dampness in the attic.
Missing, Cracked, or Curled Shingles: Inspect for damaged or missing shingles, especially after a storm.
Damaged Flashing: Look for rust, corrosion, or gaps in flashing around chimneys, vents, or skylights.
Sagging or Uneven Rooflines: A sagging roof could indicate structural problems.
Granule Loss: Excessive granules in gutters suggest aging asphalt shingles.
Moss or Algae Growth: Can trap moisture and damage roofing materials.
How do I choose the right type of roof for my climate?
Consider your local climate when choosing a roof:
Hot Climates: Opt for light-colored or reflective roofing materials to reduce heat absorption. Consider tile roofs for their thermal mass and heat resistance.
Cold Climates: Ensure your roof has adequate insulation and ventilation to prevent ice dams and moisture buildup. Metal roofs can shed snow effectively.
High-Wind Areas: Choose roofing systems with high wind ratings and properly installed hurricane straps or clips to enhance wind resistance.
Areas with Heavy Rainfall: Ensure your roof has proper drainage and a waterproof membrane to prevent leaks.
